摘要： A system and a method for acquiring image data of a subject with an imaging system is provided. The system can include a gantry that completely annularly encompasses at least a portion of the subject, with a source positioned within and movable relative to the gantry. The source can be responsive to a signal to output at least one pulse. The system can include a detector positioned within and movable relative to the gantry to detect the pulse emitted by the source. The system can also include a detector control module that sets detector data based on the detected pulse, and an image acquisition control module that sets the signal for the source and receives the detector data. The image acquisition control module can reconstruct image data based on the detector data. The signal can include a signal for the source to output a single pulse or two pulses.

摘要： The present disclosure relates to a device for closing and opening a beam path of electromagnetic and/or ionizing radiation, comprising at least one part of a shutter body which is permanently situated in the beam path and rotatable about a longitudinal axis situated essentially transversely with respect to the beam path, and which contains a material that is opaque to the radiation and blocks the beam path when the shutter body is in a closed rotary position, and which defines a passage that is transparent to the radiation when in an open rotary position; and comprising a magnetic drive which is coupled to the shutter body for rotation of same about the longitudinal axis between the rotary positions. The magnetic drive is an electromagnetic drive, and is configured for moving the shutter body between the rotary positions, wherein at least one of the rotary positions corresponds to a stable position of the magnetic drive which maintains the magnetic drive without current.

摘要： A method, apparatus and system for decreasing random motions of a levitated diamagnetic cylinder is provided. Embodiments of the present invention utilizes a parallel dipole line (PDL) trap system to trap a diamagnetic object. The trap consists of a magnetic parallel dipole line system made of a pair of transversely magnetized (or diametric) cylindrical magnets. A diamagnetic object such as graphite rod can be trapped at the center. The system includes a differential photodetector pair, a differential amplifier, a differentiator, a proportional integral differential (PID) feedback controller and electrode voltage drive system. The feedback control system will minimize the speed of the trapped rod thus lowering its effective temperature. The system can be used to minimize intrinsic noise and enhance the precision in various sensing applications using a parallel dipole line trap.

摘要： A satellite-based missile defense system includes a neutron beam transmission tube, a beam generator disposed within the neutron beam transmission tube and operable to emit neutron beamlets from a neutron source. A first collimating plate is disposed within the neutron beam transmission tube and downstream from the beam generator. A second collimating plate is disposed within the neutron beam transmission tube and downstream from the first collimating plate. Neutron beams can be used to create gamma radiation and which can in-turn disable electronic equipment, such as that found in enemy aircraft, missile guidance systems, communication systems and/or the like.

摘要： A laser system may include a laser source configured to generate a laser light beam and an acousto-optic modulator (AOM). The AOM may include an acousto-optic medium configured to receive the laser light beam, and a phased array transducer comprising a plurality of electrodes coupled to the acousto-optic medium and configured to cause the acousto-optic medium to output a zero order laser light beam and a first order diffracted laser light beam. The system may further include a beamsplitter downstream from the AOM and configured to split a sampled laser light beam from the zero order laser light beam, a photodetector configured to receive the sampled laser light beam and generate a feedback signal associated therewith, and a radio frequency (RF) driver configured to generate an RF drive signal to the phased array transducer electrodes so that noise is diverted to the first order diffracted laser light beam based upon the feedback signal.

摘要： An apparatus for generating electromagnetic radiation comprises a polarizable or magnetizable medium. A polarization or magnetisation current can be generated, in a controlled manner, whose distribution pattern has an accelerated motion, so that non-spherically decaying and intense spherically decaying components of electromagnetic radiation can be generated. The coordinated motion of aggregates of charged particles can give rise to extended electric charges and currents. The charged distribution patterns can propagate with a phase speed exceeding the speed of light in vacuo and that, once created, such propagating charged patterns act as sources of electromagnetic fields in precisely the same way as any other moving sources of these fields. That the distribution patterns of these sources travel faster than light is not, of course, in any way incompatible with the requirements of special relativity. The superluminally moving charged pattern is created by the coordinated motion of aggregates of subluminally moving particles.
